As a fake geek, there are many kinds of electronic products. As a smart home, smart light bulb can attract me. It has used many products, including Xiaomi's Yeelight Blue , also paired with Bluetooth Ike E-light smart bulb , also used the ZigBee to Wi Fi bulbs. These bulbs have the same feature: they need to link to the network. I was attracted by the title of this Hey Lamp until its appearance【 Bulbs without networking 】.

       When I saw the online trial, I opened it without saying anything. Unexpectedly, I won. Thank you Mantian God Buddha, thank you Monarch 。。。。

A simple package for receiving the goods

The simple packaging may have something to do with the price, It is said that at present, the price of Heideng has reached 39 yuan, and the founder Zhang Lei's goal is to make the monochrome Heideng 19 yuan or even lower. With the optimization of circuit and the improvement of integration, Zhang Lei hopes that Heideng will sell for 9.9 yuan in the future. Of course, this price package can't be perfect, but that's not the point. Don't pay too much attention to these small details.

Turn the box around,

The package is very simple, even the description is very simple, a name, a two-dimensional code, a simple product introduction. Unpack the box: the configuration is simpler.

Inside the box are two two-dimensional code stickers and one light bulb, which is simple.

Finally, the installation is started. The location is in the company (the boss and his wife went on a tour, and the office was just messing around~~~~). You can test whether the noise within the normal range can be recognized by the light bulb.

Turn on the power, and then scan the QR code on the sticker. An H5 page appears.

Simple controls Simple buttons. ON OFF I want to know for sure that the two plus signs on the side are color temperature control, and the disk on the top can rotate to control brightness.

The first one is the warm light color. The light bulb on the side is for comparison (normally the cold light color is white)

Try adjusting the brightness

Turn the brightness down.

Then adjust the color temperature here.

It turns cold.

One day, I felt very sensitive after the test. When I was working in the office, my voice, printer voice, typing voice and so on were all noise sources. However, I was about 5 meters away from the light bulb, and the mobile phone control was very sensitive, only occasionally lost consciousness once or twice. Of course not If it is installed in a closed lamp shade or in a place where the sound is blocked, it will not work properly.

In order to understand this principle, I found some data.

This is a microphone to pick up the voice of mobile phones.

"Jojo Jojo" is the language of Hedeng. Basically, any device that can make sound can control the Hei light. After doing experiments, turn up my computer and play the control sound I recorded, the Hei light can also be controlled. It's amazing.

     This lamp is very simple to use. If I produce an rgb color bulb, I will definitely buy one. I hope it can be better and better!  

Finally, I would like to thank Jun Jun and Lei Feng.com for giving me this chance to try!
